The aux out 1 was set to water temp 40-55c non inverted, pwm turned off. It started okay and idled at 1400 rpm but as soon as i got going. The rpms never came down bellow 2k again. Then i inverted the water temp to see if anything changes... Nothing. Left it inverted over night to see if it will work from cold start. Still does the same thing even with the idle screw closed fully.

I did see people reduced fuel to get the idle lower... well i tried running E85 at 16:1 (gasoline gauge) so...thats lean enough.

Here is my original map before i changed the #1 aux to the above settings.

Had you adjusted the idle screw before changing over to allowing the stock ecu to control idle?

If so do you know how many turns you have adjusted it by? Might be worth putting it back to how it was before. I've not had to touch the idle screw (or do you mean the throttle screw?) or anything on the mani for that matter. Just set the adap pnp board jumpers to stock ecu to control idle and adjusted the aux 1 and digital inputs as per the info on the adap forum.

Do you have your current map available rather than the one from when the adap was controlling idle?

Skir check out the end of last page for everything I've tried with no luck. I ran it for 2 days with no luck so I'm back to adaptronic idle control. The reason why i switched back was not just because it wasnt working but because my car was still dying when the fans turn on or i lower both windows at the same time.

As it's dying when the windows are operated or the fans turn on if you've got the settings as described in that thread on the adap forum it sounds like the stock ecu is simply not controlling idle when it should be. The alternator should provide more juice for those actions when required. Have you contacted Andy at Adap as maybe the board is faulty, his e-mail is tech @ adaptronic.com.au

As an extra thought I guess you are using v9 of the firmware and wari software?

Yes i switched to a v9 3 weeks ago. Didnt notice difference in the way the car runs. Just looks a bit more plushy since it can convert psi to kpa and C to F. Other than that... well thats about it.

Skir i'm assuming u're running on stock ecu? mind sending me your ecu file so i can check the rest of your aux/ins?

Hey guys today i screwed around with my fans a bit.... i got aux 6 to be the drivers fan and aux 7 to be the passenger fan. The settings i see on the other page are showing aux 7 as none and showing aux 8 as the passenger fan. You guys might want to check out and make sure both fans are turning on as you're not just running on a single fan with no backup.

From what I understood initially, this feature only worked with NB8B? Are these not the 2001-2005 Miata. If you have an 99-00 it doesn't work? Tripple don't you have a 99? What am I missing?

Also, forgive my computer ignorance but what do you exactly do with the jumpers? Do you unplug the black pieces and plug them into the stock bottom row? Or is it a type of switch that you push down?

Yes the black plugs are the jumpers. Warning : disconnect the battery or the Adapt before moving the jumpers.
I had almost perfect idle under the 420 closed lop control (2003 1.8 UK spec) except it had a tendency to die when I turned on the headlights. Changing to the stock ecu for idle control has resolved that issue and idle is perfect. I did have to adjust the throttle by-pass to get the warm idle correct. It starts first time and idles hot or cold. This is with a Rotrex and running stock injectors.

Does work with 01+ but some of the harnesses they made didn't have the option on them

By switching the jumper on the harness board like anyone else with the stock idle option board.

There were 2 batches of harnesses, the 1st one didnt have the option, the 2nd one did for all models. Thats the one i got and its PNP for 99-00

What settings did you use for this please?

aux 6 water temp 90-93
aux 7 water temp 93-96 (never used ac however if you do use it make aux 7 to be "or 10/11" and make aux 10 to be 93-96)
aux 9 water temp 89-91
aux 10 water temp 92-94
aux 11 ac

Since i was using the 420 to control idle my digital inputs were as follows to boost rpm a a sec before the fans turn on (only way i've ever found to keep the motor running when the fans initially would hit).
digital inputs 6,7, as none (act low)
digital input 9 electrical load 2 act hi
digital input 10 electric load 3 act hi
digital input 11 electric load 3 act hi

Since u have a vvt model i dont know what aux your vvt control is at.

Boy am I upset I haven't tried this when this was first brought up. Thinking it wasn't applicable on 99-00 miatas and lack of room to see or work on the board kept me from checking. I used Andy's aux out and input settings and idle works flawless now with lights and windows used.

I had a couple problems though;

1. When I turned AC on, revs go from 1000 to 1500 rpms or higher.
I tried correcting this by inverting aux out 1. Rpms went down to go back up.
I also tried lowering the extra effort for elec. load 2 and 3, from 4 down to 0 with no difference at all.

2. After doing this and messing around trying to get idle down while AC on I noticed my temp gauge spiked a lot higher than ever before. It went to 225F/107C just sitting idle on a breezy cool day. The temps usually don't go above 210F/98C on a super hot day sitting in traffic. Do you think 225F for two minutes was hot enough to cause engine damage?

What most likely caused these issues and how can I go about correcting it?
Also I don't understand why output and input settings above 9 fonts are grey as if it's not functional when below 9 they are black.

Forgive me if some things have been explained already but a lot about ecu tuning confuses me.

Here are my settings. Let me know if you see anything that needs to be adjusted.

Aux 7 should be your secondary fan so it should be an OR 9/10.

Like i said aux 7 is the passenger fan, not aux 8 like andy says so. Check it out your self. Set aux 7 to none and click inverted. Passenger fan will power on.

You can't damage an motor with 225f water temps as that's what a stock miata will see all summer in most places, I see higher on my stock 02. You need to set your water temps on aux9 and aux11 way lower, like 83/85 lower. you fans are coming on at about 200 and turning off at 195.

Jeff ur stock fans run at 96 and 101 for the passenger, 83 is way way too low. thats 181 degrees... at that temp the thermostat barely opens.
